Leverless load-bearing rotating mechanism

Abstract

Disclosed in the invention is a lifting-lever-free type bearing rotary mechanism comprising a fixed shaft, a rotating wheel, a first spring plate, a second spring plate, an intermediate connection sleeve, a bearing sleeved ring, a driving assembly and a first fixed element, a second fixed element, a third fixed element, and a fourth fixed element. The fixed shaft is installed at a rack body. The rotating wheel, the first spring plate, the intermediate connection sleeve, the second spring plate, and the bearing sleeved ring successively sleeve the fixed shaft and can rotate relatively to the fixed shaft. The driving assembly is installed at the rack body and drives the rotating wheel to make rotation. One end of the first fixed element is fixedly connected with the rotating wheel and the other end is fixedly connected with the first spring plate; one end of the second fixed element is fixedly connected with the first spring plate and the other end is fixedly connected with one end of the intermediate connection sleeve; one end of the third fixed element is fixedly connected with the other end of the intermediate connection sleeve and the other end is fixedly connected with the second spring plate; and one end of the fourth fixed element is fixedly connected with the second spring plate and the other end is fixedly connected with the bearing sleeved ring. A to-be-detected object is carried at the bearing sleeved ring. Therefore, the lifting-lever-free type bearing rotary mechanism has advantages of simple structure, flexible rotation and low cost.

Description

technical field [0001] The present invention relates to a bearing rotating mechanism, in particular to a lever-less bearing rotating mechanism. Background technique [0002] As we all know, in order to improve the wear resistance of disc cutters, in addition to reasonable design on the material of disc cutters and the manufacturing process of disc cutters, another best way is to add The saw teeth are welded with wear-resistant hard alloy welding pieces or diamond welding pieces, through which the saw teeth of the disc cutter are more wear-resistant, so as to reduce the use cost of the disc cutter. [0003] Among them, in order to detect whether the serrated teeth of the welded disc cutter meet the standard requirements, it is necessary to perform various tests on the disc cutter, and the radial runout test is one of the various tests. In the equipment for radial runout detection, a bearing rotation mechanism for carrying the disk cutter and driving the bearing disk cutter t...

Problems solved by technology

[0004] However, the structure of the existing load-bearing rotating mechanism for rotating the disc cutter is more complicated, and its rotation is also relatively clumsy; just because of the clumsiness, it is necessary to increase the rotary gear shifting mechanism to carry out the gear shifting operation for the disc cutter, further greatly increased the cost
